Im looking to set up either a grouped/bundled product that contains 4 simple products.
In this grouped/bundled product the customer can choose the quantities of these 4 simple products that add up to 12.
Football - Red - QTY = 2Football - Blue - QTY = 4
Football - Green - QTY = 3
Football - Pink - QTY = 3
Basically the customer can choose the quantity of the listed products but it has to add up to 12 for the customer to add it to the cart,
Did you check this extension if that helps?
